Be it known that I, THOMAS W. HOLLEY, a citizen of the United States,residin at Ranger, in the countyof- Eastland and state of Texas, haveinvented certain new and useful Improvements in Pedestals for Sand- ReelShafts, of which the following, is a specification.

The present invention relates to bearings and more particularly topedestal bearings for the tail end of sand reel shafts.

It is now common practice to support the shaft of sand reels at one endby a wooden tail post framed to a sand reel tail sill which is in turnsupported on mud sills of the well drilling rigs. The tail post isusually of oak and has a hole bored transversely into its sideconstituting a bearing for the sand reel shaft. As a result the woodwears away the hole becoming enlarged so that there is considerable objectional play and which ultimately necessitates the replacement of thepost or the provision of a bushing or some filler about to split sincethe bringing of the sand reel into use subjects the post to considerablestresses and strains incident 'to raising of the bailer and forcing ofthe sandreel pulley into such frictional engagement withband wheel as tofunction properly. Furthermore, with this type of tail post, it is notalways possible to erectjthe'rig 'and dispose the post so that it is inproper, relat on to the band wheel that there will be good intinmatecontact between the band wheel and pulley and much time and labor may beconsumed in adjusting parts so that the sand reel pulley will not undulywear the band wheel. a

One of the principal objects of my invention is to provide a pedestalfor sand reel shafts which may include the usual tail sill, mud sillsand a modified tail post,'adapted to carry a bearing which may bereadily adjusted vertically and longitudinally of the rig and held firmin the adjusted position against accidental displacement incident to useof the rig. In this connection it has been found that vibrationandforces coming upon the rig is apt to cause displacement of theordinary sand reel tail sill and'tailpost and. consequently adjustmentsmust be made if sand reel shaft.

the shaft. The wood is apt PEDESTAL nos SAND-REEL snarrsfl Applicationfiled February 10, 1921. Serial 110.4%,029.

the efficiency of the apparatus is to be tained at av maximum. j Anotherobject of the invention is to provide a pedestalfor said reel shafts inwhich a metallic bearing block isprovided adapted to receive an alloylining such as Babbitt metal, since this hearing must serve as a pivotfor the tail end ofthe sandreel shaft. This lining may be. readilyreplaced or remelted and used. again, when necessary to provideasubstantial bearing.

Other objectsyand advantages ofthe in ventlon will appear'in thefollowing detailed description taken in connection with the accompanyingdrawings, forming a part of this specification, in which drawings:

The 1nvent1on. is herein shown {as applied to what is commonly knownasthe standard.

rig, in which the sand reel shaft E is disposed with its axis extendingdiagonally cross wisethe longitudinal 3X18 ofthe base of the rig, but itis to be understoodthat the.

principle of this invention maybe applied. other types of rig,withoutdeparting from the spirit of the invention; It is understoodthat, in practice,'the sand reel D is used for the purpose of loweringand raising a sand pump or bailer, not shown in the drawings,

and this isaccomplished by moving the shaft t, as by shifting thebearing 8 of pedestal H so that the pulley F is moved into and out ofengagement with the band wheel G. i

The particular type of pedestal H shown in Figure l of the drawingdoes'not form'a part of the present invention, but is more specificallydisclosed in my co-pending application for patent filed on the tenth dayof February, 1921, Serial Number 444 030, It is shown merely by way ofeXample'to indicate that the bearing 8 maybe shifted longitudinally ofone ofthe main sills B, as by mechanism 9 so that the pedestal Jembodies the pivotal bearing for shaft in, ashereinafter noted. Thepresent invention is desig natedby character J. i

The pedestal J, in addition to the mud sills C, in the example shown,comprises a tail sill 10, tail post-11, bearing block 12, means 13 foradjusting the bearing block longitudinally of post 11, means 1d forsecuring the bearing block 12 to the post 11 in adjusted position, andmeans 15 bracing the block 12 fromthe mud s lls (l.

As is the usual practice, the mud sills (J are shown in spacedapartrelation, and the tail sill 10. may be of ordinary formation, supportedby these mud sills in adjusted relation, as by wedges l6.

' The tail post 11 may be carried by tail sill 10 in the usual manner,that is, by having its lower portion dove tailed as at 17, received in arecess. 18 in the sill, a wedge 19 being provided to hold it in fixedrelation i to the sill. It. ispreferred to-provide this post with a seat20 and an'upright abutment 21 laterally of said seat and this may wellbe accomplished byreducingtheupper end port on or the tail post,asiclearly shown in are 4 of the drawings. I

.rieferring now to the bearing block 12, it is preferably made of metal,and is provided with a shaft receiving openingQQ, prefer ably lined withBabbitt metal 23, this op'ening receiving the end portion ofthe sandreel shaft E. In the preferred emboi ilinlent of the invention, and fora purpose to be subsequently set forth, this bearlng block is,

also, provided with transverse ways 24, vertical ways25 and recesses 26open at each end of the block and intersecting the axes of ways 25 Theways 24: are arranged in pairs one pair. being above the opening 22-andthe other pair therebelow. are provided 'a djacentthe ends of the block,one at each side of the opening 22., The

The vertical ways 25 block 'lQis adapted to be supported by the seat 20of the post, asjby resting directly thereupon, or when adjustment is,desired vertically, there may be interposed bet-ween I the block and theseat. filler pieces 27. The

bloclr'is also adapted to engage the abutment the 2L and when in use isheld firmly against this abutment and in supported relation to the seat20.

As suitable means for adjusting the block longitudinally of the post 11,the means 13 is provided and comprises vertical rods 28, one each sideof the post 11 and nuts '29, 30, 31' and 32- in screw threadedengagement with these rods for the purpose of holding them in fixedadjusted relation with respect position with respect to block 12,;whilenuts 32 engage the under side of the sill; 10. It is thus to be notedthat, by releasing either nuts 31 or 32 and rotating either nuts 29 or30, the block 12 may be raised with respect to seat 20 and after in thedesired. adjusted position, the nuts which have been released may betightened, thus holding the block firm in adjusted'positi'on towardjorfrom sill 10, and n a manner to be securely supported by the seat 20.

After the block h'asbeen adjusted in a. vertical direction, it may besecured to the bearing block 12, as by meansld, which, in the exampleshown, comprises a pair of U-shaped members '33 which .embrace the post11, the stems 34 of these members 38 extending through thetransverseways 24in the bear-i ing block, and provided with nuts 35 inscrew threaded engagement with the end;

portions of stemsBeh-c t j The bearings for the shaft of sand reels aresub ected tostres'ses andstrains incident to lowering and raising thesand pump or bailer and the greatest pull upon the shaft is usuallyupwardly and diag'onally, in the line ofdlrection of the cable leadingofffrom brought upon the bearin [incident to bringsand reel; There [ispressure.

Ulg Of lJhG pulley F into intimate contact with the band wheel G for thetransmission of mot1on. There is also a slight. torsional stress at thebearing which acts asapivot for the ,shait, in moving the pulley F intoengagement with band wheel G1 but thislis mayremain rigid even. wh nsubjected to,

these forces, and-also to prevent longitudinal movementfof the tail{sill with respect to the mud sills. Suit-able means for this purpose isdesignated generallyby the character 1;?

and in the example shownis in the form of two tens oning devices 36, onefor each end taken up, to a large extent, byflthe Babbitt of the bearingblock 12. Each tensioning device comprises a rod 37, having an eye 38adapted to fitin the recess 26 in bearing block 12 and to receive thevertical rod 28,.

as clearly shownin Figure (5 of the drawings; a turnbuckle 39 in screwthreaded-engagement with rod 37 at its end portion with the bearingblock 12, as by engagement of its eye 38 with the vertical rods 28; theturnbuckle 36 provides for minute adjustment of the tensioning device;and the chain 41 and the hook 42, provides for major adjustments. Whenerecting the rig, if it is necessary to move the tail sill 10'transversely of the mud sills C as by releasing the wedges 16, in orderthat the pulley F may be disposed in proper relation to the band wheelG, for successful operation, the hooks 42 may be disengaged from thelinks of chains 41 and after proper adjustment is had, the hooks may bedisposed in operative relation to the links of the chains which are mostsuited for their reception, and the turnbuckles 36 may then be rotatedto draw the eye bolts and rods 37 of each tensioning device toward eachother.
